~donmcc/astr: Make `va_list` parameters `const`.

5ed773f7d4d048ebea586fb9432b907d3aff24ac — Don McCaughey 2 years ago 0a436b7

Make `va_list` parameters `const`.

The functions `astr_formatted_length_from_va_list()`,
`astr_realloc_append_formatted_from_va_list()` and
`astr_alloc_formatted_from_va_list()` are already defensively copying
their `va_list` parameters, so make these parameters `const` to
communicate this.
